SPECIFICATION forming part of Letters Patent No. 349.229, datedSeptember 14, 1886.

Application filed January 19, 1886, Serial No. 189.040. (No model.)

To @ZZ whom, it may concern:

Be it known that I, VICTOR LORD, a citizen ofthe United States, residingat Odessa, in the county of New Castle, State of Delaware, have inventeda new and useful, Improvement in Mechanism for Preparing Rock, &c., forFertilizersand Cements, which improvement is fully set forth in thefollowing specification and accompanying drawings, in which- Y Figure lrepresents a partial side elevation and partial vertical section ofmechanism for preparing rocks, Src., for fertilizers and cementsembodying my invention. Fig, 2 represents a partial top or plan view anda partial horizontal section thereof, Figs. 3 and 4 are views ofdetached parts.

Similar letters of reference indicate corresponding parts inthe severalfigures.

Myinvention consists of mechanism for preparing rooks, &c., forfertilizers and cements, wherein provision is made for separating thefine and coarse particles thereof and collecting the same and returningthe coarse particles to the mill to be reground and again sub- 25 jectedto the bolting operation, as will be hereinafter fully set forth andclaimed.

Referring to the drawings,'A represents a mill for breaking or crushingrock, cement, &c., thesame being in communication with an elevator, B,by means of a pipe o r tube, C.

Connected with the top of the casing of the elevator B, is a chute, D,which extends in an inclined direction to a box or case, E, which isadjacent to a bolt, F, the latter being properly mounted and operated inany suitable manner. On the under side of the chute D is a sieve, G, andbelow the same is a spout, H,

which is connected with a pipe, J, the latter entering the bolt F.

K represents an elevator, which is properly supported, and has the upperendl of its casing in communication with a separator, L, for tine andcoarse particles of roclg, Src., supplied to the elevator from' thegrinding mills M, which latter are in communication with the elevator bymeans of pipes or spouts N. The separator L is formed with compartmentsL2 L. At the top. of the compartment L2 is a sleeve, P, and at thebottom thereof a pipe, Q, which leads to a fan, R, the latter beingproperly supported.

Connected with a branch of the fan-case is pipe, T, the pipe S leadingtothe elevator B and the pipe T to a bag or case, U, the upper portionwhereof is formed of burlap or other similar material, the bottom ofsaid bag having a discharge pipe, U'.

Adjacent to the bag U is a bag, U2, which is in communication withsaidbagU bymeans of a pipe, U3, of burlap or other suitable material,said bag U2 having a discharge-pipe, U", both bags being properlysupported.

Connected with the bag U2 is a pipe, V, which leads to a chest, W, andleading from said chest is a pipe, X, which opens into the atmosphere,said pipes V X being formed ot' burlap or other suitable material. Thebolt has different grades of meshes, and below the same are chutes Y Z,the chute Y directing the fine material that has been bolted to a placeof-eollection, and the chute Z being in communication with a pipe, Z',which leads to one of the mills M. The lower end ot' the bolt hasadjacent to it a chute, A', the same having connected with it a pipe,B', whose lower end is in communication with the case of the elevatorK.v It is remarked here that a series of balls, C', are employed in thebolting opera tion, the same being directed into the bolt so as to acton the material therein, and to assist to bolt the same, said ballsescaping into the chute A', and then entering the pipe B', from whencethey are directed into the elevator K, and conveyed to the separator L,where, rolling over the sieve l?, they reach the pipe J, and are socaused to re-enter the bolt. The bottom of the case E is inclined, as atD', and to the side of said case, near the lower. end of said bottom, issecured pipes E', which lead to the mills M.

F' represents a shaft, which is provided with pulleys whereby power maybe communicated to certain parts ofthe bolting mechanism, said shaftbeing properly mounted above the sepa` rator L, and carrying jogs G',which engage with a collar on a rising and falling arm, H', whose lowerend is attached to a projection, J', on sieve l). This proj ectionpasses through the top wall of the separator L, and is adapted tovibrate the sieve l) therein for assisting the action of said sieve.

In the horizontal part of the pipe X, where it leaves the chest W, areopenings K', forming a pipe, S, and with the wall of the case is a IOOoutlets for directing the fine bolted material from said pipe.

The operation is as follows: The rock, cement, Src., is broken orcrushed in the mill A, and is directed by the pipe C to the elevator B,by which it is conveyed to the chute D. The finer particles fall throughthe sieve G- into the spout H, and are. passed by the same through thepipe J into the bolt, from which the fine particles fall into the spoutY, andare thus directed to a place ot' collection. The tailings from thebolt enter the spoilt Z, and are conveyed by the pipe Z to one of themills l\'l,whcre they are ground. The coarse particles in the chute Descape into the case E, and are directed by the inclined bottom thereofto the pipes E', and so reach the mills M, wherein they are ground. Thematerials ground by the mills leave the same and reach the elevator K bymeans ofthe pipes N, and enter the separator L, where the tine particlesescape through the sieve P into the compartment L, and so reach the pipeQ, whereby they are conveyed to the fan R. The coarscr particles passover the sieve P and enter the compartment L, and escape therefrom intothe pipe J, thus reaching the bolt F,where they are subjected to thebolting action, the tine particles and tailings dropping into thespoutsYZ, from whence they are collected and reconveyedsimilar to the materialadmitted to the bolt through the chute D. The light material from thepipe Q reaching the fan is blown by the latter into the pipe or chute T,and from thence into the bag U. \Vhatever heavy material enters the pipeQ and leaves the fan-case with thelighter particles, drops into the pipeS, so as to reach the elevator B, and thence the chute D, and eventuallyone of the mills M, where it is reground. Some of the light material inthe bag U is blown through the pipe U3 into the bag U'i, then into thechest lV, and tnally through the pipe X, where it is discharged at thespouts or openings li into suitable bags, ezc., provided to collect thesame. The main portion of the light material admitted into the bags orhoppers U U" escapes through the discharge-pipes U U at the bottomthereof, whereby it may be collected in any suitable manner. The airdriven into the bags U Ul and pipes U3 and V serves to keep the tineparticles from matting, but escapes through the burlap or material ofwhich they are formed, avoiding blowing of said particles into theatmosphere at the outer end of the pipe X, said end, however, permittingthe escape of what little air enters said pipe. Should the bolt berendered unserviceable from any cause, the sieve or screen P is raisedor removed, and the material from the elevator K is discharged into thecompartment L2 of the separator and directed into the pipe Q, which isprovided with a valve or cut-ofi', M,which, being opened, permits theescape of the material into a pipe or chute, M, which leads from thepipe Q. to the spout Y, and conveys the same to the latter, from whichit may be discharged.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
